PROJECT SYNOPSIS

Problem

Mounting concerns about the safety and security of critical infrastructure have resulted in an intricate ecosystem of cybersecurity guidelines and policies, as well as directives and compliance measures. By definition, such guidelines and policies are written in linear, sequential text form—word after word, chapter after chapter—often with different segments thereof presented in different documents in the policy ecosystem. In general, the design and description of target CPS-structures are also in text form. This situation makes it difficult to integrate or even to understand the policy-technology-security interactions. It also impedes effective risk assessment. In short, individually or collectively, these features inevitably undermine cybersecurity initiatives. Missing are fundamental policy analytics to support CPS cybersecurity and reduce barriers to policy implementation.

Goals

The overarching goal of this project is to develop analytical methods to strengthen cybersecurity policies in support of the national strategy for cybersecurity, as outlined in Presidential Executive Orders and National Defense Authorization Acts.

Operationally, the goal is to create policy analytics for cybersecurity, designed to:

1. Overcome the limitations of the conventional text-based policy form,
2. Extract metric-based knowledge embedded in policy guidelines and/or distributed in policy-ecosystems,
3. Align policy directives to intended targets in the relevant CPS structure, and
4. Assist the users on "how-to" connect cybersecurity policy to CPS properties and facilitate implementation.

Strategically, our goal is to construct a suite of tools for application to policy directives, regulations, and guidelines across diverse CPS domains and properties. The intent is to help users address mission-related challenges, concerns or contingencies.

Challenges

The research challenge is three-fold, namely to:

1. Develop structured system models from text-based descriptions of system properties
2. Transform policy guidelines and directives from text to metrics
3. Connect Policy directives to CPS properties.

Addressing these challenges essential in order to:

• Identify major policy-relevant CPS properties and parameters,
• Situate vulnerabilities and impacts,
• Map security requirements to security objectives, and
• Support responses of CPS to targeted policy controls.

Data & Proof of Concept

Our "raw" data base consists of major policy reports on CPS cybersecurity prepared by the National Institute for Standards and Technology (NIST) as well as NIST analyses of CPS properties. Clearly, considerable efforts are always being made to "mine" NIST materials; however, few initiatives explore the potential value-added of drawing on multi-methods for knowledge extraction and/or of developing analytical tools to support user understanding of policy directives, analysis, and eventually to enable targeted-action. While our approach appreciates and is informed by such efforts, it is distinctive by developing a suite of cybersecurity policy analytics—based entirely on metricized text  of policy documents—and applied to metricized models of CPS. The "proof of concept"  focuses on analytics for cybersecurity policy applied  to smart grid for electric power systems.

BACKGROUND & FOUNDATIONS

The research initiative on Explorations in Cyber International Relations (ECIR) provides background and foundations for this Project. A collaboration of MIT and Harvard University, with Nazli Choucri as Principal Investigator, ECIR was completed under a Minerva Project of the U.S. Department of Defense (2009–2014).

The research problem is this: distinct features of cyberspace—such as time, scope, space, permeation, ubiquity, participation and attribution—challenge traditional modes of inquiry in international relations and limit their utility. The interdisciplinary MIT-Harvard ECIR research project explores various facets of cyber international relations, including its implications for power and politics, conflict and war. 

The primary mission and principal goal is to increase the capacity of the nation to address the policy challenges of the cyber domain. Our research is intended to influence today’s policy makers with the best thinking about issues and opportunities, and to train tomorrow’s policy makers to be effective in understanding choice and consequence in cyber matters.

Accordingly, the  ECIR vision is to create an integrated knowledge domain of international relations in the cyber age, that is (a) multidisciplinary, theory-driven, technically and empirically; (b) clarifies threats and opportunities in cyberspace for national security, welfare, and influence; (c) provides analytical tools for understanding and managing transformation and change; and (d) attracts and educates generations of researchers, scholars, and analysts for international relations in the new cyber age.

RESULTS, PRODUCTS & ARTIFACTS

Project results and  products include, but are not limited to: (a) methods to examine the implications of cybersecurity directives and guidelines directly applicable to the system in question; (b) information about relative vulnerability pathways throughout the whole or parts of the system-network, as delineated by the guidelines documents; (c) insights from contingency investigations, that is, "what...if..."; (d) design framework for information management within the organization; and (e) ways to facilitate information flows essential for cyber security-related decision.

Results To Date

Thus far, we have aligned the project vision and mission to the priorities of the Program on National Cybersecurity Policy and identified the overall policy-relevant ecosystem. By focusing on national cybersecurity policies for securing the nation's critical infrastructure, we identified the policy ecosystem and core policy documents pertaining to smart grid for proof of concept. 

We have extracted text-based data and created a metric-based Dependency Structure Matrix (DSM) of the "as-is" NIST’s reference model for Smart Grid. We also completed the design and operational strategy for our data extraction and linkage method. This involves developing the method for moving from "policy-as-text" to "text-as-data" in the process of constructing the Suite  of Policy Analytics for CPS cybersecurity. 

In short, we created (a) metric-models of policies and guidelines, (b) metric-models of CPS and captured (c) value-added of applying policy directives to CPS properties. Each was based on a set of pre-tests—executed in operational form—and provided foundation for the next step.

In the process, we developed rules and methods for extracting and metricizing data from text-form documents, and then constructed the necessary issue and policy-specific linked database for the relevant policy-ecosystem.

Jointly, these steps allowed us to create (i) initial exploratory tools for analysis of system information, and (ii) core dependency matrix (DSM) of the CPS based on the identification of first-level information dependencies. The DSM was (a) examined and validated, (b) further transformed as needed into clusters and partitions of structure and process, in order to (c) explore CPS properties for policy and reveal interconnections and "hidden features."

The forgoing served as the basis upon which added policy imperatives—also in text form—are incorporated in expanded DSM forms.

Throughout, we have addressed critical research tasks, notably (i) identifying and undertaking essential corrections; (ii) replicating the core structured DSM model for validation purposes (iii) extending the core DSM to span greater system structure (iv) conducting  general applications of project methods and (vi) explore alternative approaches to automation of the entire research process.

Contributions to Hard Problems

Our major contribution is to the hard problem of policy governed collaboration, with secondary contributions to the other hard problems. We examine the value of "text-to-metrics" in a complex cyber-physical system where threats to operations serve as driving motivations for policy responses.

This Project directly addresses the hard problem of “policy-governed secure collaboration” with proof of concept at the enterprise level (smart grid for electrical power systems The figure below displays the near-, mid- and long- term Project goals (arrow format). The first grey bar (tope) shows “Policy Governed Secure Collaboration” as its primary hard problem across all research periods. The figure also shows where the four other hard problems (grey bars) align with and across the research phases (the arrow format).

Project design—research phases in relation to SoS hard problems.

It is especially relevant to the Science of Security & Privacy Program because the work plan is anchored in metricized policies then applied to the CPS model in order to (a) situate salient system-wide properties, (b) locate vulnerabilities (c) map security requirements to security objectives and (d) advance research on how multiple system features interact with multiple security requirements and affect the cybersecurity critical cyber-physical enterprises.

Potential Applications

Two issues were raised by NSA staff and discussed with the Project PI:

1. How can the methods and techniques being development  (or have developed) for Policy Analysis for Cybersecurity of Cyber-Physical Systems assist in creating an Automatic Compliance Monitoring Application? The goal would be to place on a system running data analysis applications (analytics), with the purpose of ensuring that those analytics are complying with all relevant policies and regulations.
2. How can the Project research approach be used for applications to analytics of NIST Privacy Framework.
